Method and Device for Transmitting Sci in Nr V2x

2. The method of claim 1, wherein the first PSCCH and the first PSSCH are transmitted to reserve the second resource.

3. The method of claim 1, wherein a number of subchannels included in the first resource is less than a number of subchannels included in the second resource.

4. The method of claim 3, wherein the number of subchannels included in the first resource is one.

5. The method of claim 1, wherein the first SCI transmitted through the first PSCCH includes information informing that the TB is not transmitted through the first PSSCH.

6. The method of claim 1, wherein the first device informs that the TB is not transmitted through the first PSSCH, based on a combination of information related to modulation and coding scheme (MCS) included in the first SCI transmitted through the first PSCCH and information related to redundancy version (RV) included in the second SCI transmitted through the first PSSCH.

7. The method of claim 6, wherein the information related to the MCS is 26, and the information related to the RV is 1.

8. The method of claim 1, wherein the second SCI transmitted through the first PSSCH is rate-matched on a resource related to the first PSSCH.

11. The method of claim 10, wherein the N-th symbol is a symbol to which 1st DMRS is mapped on the resource related to the first PSSCH.

15. The first device of claim 14, wherein the first PSCCH and the first PSSCH are transmitted to reserve the second resource.

16. The first device of claim 14, wherein a number of subchannels included in the first resource is less than a number of subchannels included in the second resource.

17. The first device of claim 16, wherein the number of subchannels included in the first resource is one.

18. The first device of claim 14, wherein the first SCI transmitted through the first PSCCH includes information informing that the TB is not transmitted through the first PSSCH.

19. The first device of claim 14, wherein the first device informs that the TB is not transmitted through the first PSSCH, based on a combination of information related to modulation and coding scheme (MCS) included in the first SCI transmitted through the first PSCCH and information related to redundancy version (RV) included in the second SCI transmitted through the first PSSCH.
